如何使用mplfinance和大熊猫ta绘制指示线？
如何使用mplfinance和大熊猫ta绘制指示线？
提问于 2022-02-21 21:38:00
我有以下代码：
import MetaTrader5 as mt5
import pandas as pd
import time
import pandas_ta as ta
import mplfinance as mpf
pd.set_option('display.max_columns', 500)
pd.set_option('display.width', 1500)
if not mt5.initialize():
print("initialize failed")
mt5.shutdown()
account="FOO"
authorized=mt5.login(account, server="FOO")
if authorized:
print("Authorized")
else:
print("failed to connect at account #{}, error code: {}".format(account, mt5.last_error()))
cndl_72 = mt5.copy_rates_from_pos("BTCUSD", mt5.TIMEFRAME_M1, 1, 72)
cndl_72_df = pd.DataFrame(cndl_72)
cndl_72_df['time']=pd.to_datetime(cndl_72_df['time'], unit='s')
cndl_72_df.rename(columns={'time': 'date', 'tick_volume' : 'volume'}, inplace=True)
cndl_72_df.set_index('date', inplace=True)
cndl_72_df.drop(['spread','real_volume'], axis=1, inplace=True)
mpf.plot(cndl_72_df, type='candle')目标是使MACD指示器出现。
编辑#1:参见注释中的尝试#1。更改会引发一个关键错误。
编辑#2:参见更改https://pastebin.com/qAiu1PkS，它将引发一个新错误：
编辑#3:类型错误修复，现在我可以成功地计算MACD从我的数据，并在必要时追加。现在我需要找出图表..。
编辑#4:图表绘制完成，请参阅注释。MACD图看起来很相似，所以数据可能是准确的。只需要让它更漂亮..。

TypeError: must be real number, not str据我所知，没有任何可能产生这种情况的字符串。我怎样才能找到源头？

工作代码：
import MetaTrader5 as mt5
import pandas as pd
import pandas_ta as ta
import mplfinance as mpf
pd.set_option('display.max_columns', 500)
pd.set_option('display.width', 1500)
if not mt5.initialize():
print("initialize failed")
mt5.shutdown()
account="HIDDEN"
authorized=mt5.login(account, server="HIDDEN")
if authorized:
print("Authorized")
else:
print("failed to connect at account #{}, error code: {}".format(account, mt5.last_error()))
cndl_72 = mt5.copy_rates_from_pos("BTCUSD", mt5.TIMEFRAME_M5, 1, 144)
cndl_72_df = pd.DataFrame(cndl_72)
cndl_72_df['time']=pd.to_datetime(cndl_72_df['time'], unit='s')
cndl_72_df.rename(columns={'time': 'date', 'tick_volume' : 'volume'}, inplace=True)
cndl_72_df.set_index('date', inplace=True)
cndl_72_df.drop(['spread','real_volume'], axis=1, inplace=True)
macd = cndl_72_df.ta.macd(close='close', fast=12, slow=26, signal=9)
